Dataset and appendix: Comparison of measurement accurancy between DGNSS and RTK

The horizontal error of RTK-GNSS positioning and the effects of GNSS receiver settings were tested under a forest canopy. The dataset of table 1 is the horizontal error of RTK-GNSS and DGNSS.The dataset of table 2 is the horizontal error of diferent SNR in RTK-GNSS.The dataset of table 3 is the horizontal error of diferent angle in RTK-GNSS.The dataset of table 4 is the horizontal error of diferent occupation time in RTK-GNSS.Appendix 1 is the horizontal error of RTK-GNSS and DGNSS on 21 survey stakes.
